So, any thoughts on whether it's okay to use plywood for more
strength or would I be better off using particle board?

I don't like voids.

That's why some folks pay more for cabinet grade or marine plywood.

To the op- I would definitely go with exterior- but if you're anal,
you can avoid having to fill any edge voids by using marine grade.
